Title: Pll circuit
Inventor: YAMAKAWA KUNIO
IPC: H04L7/02
Filed: 1987-02-02
Abstract: PURPOSE:To constitute a PLL circuit whose output is stable by detecting an omission in an input signal in the absence of the said signal so as to input an output of a loop filter just before the omission to a voltage controlled oscillator. CONSTITUTION:A switch 7 is thrown to the position (b) at the rising of the input signal and the circuit acts like a normal PLL circuit. When the pull-in is finished, the lock state is maintained and a capacitor 6 is charged up to an output voltage of a loop filter 3 at that time. On the other hand, if an omission takes place in the input signal, a level detector 9 detects it to throw the switch 7 to the position (a). Thus, a voltage at the capacitor 6 is fed to the input of the voltage controlled oscillator 8. Thus, the output of the oscillator 8 is almost unchanged and the frequency and phase at the lock state are maintained. If the omission of the input is eliminated, the detector 9 detects it to thrown the switch 7 to the position (b). Thus, a stable output is obtained.

Title: Liquid-cooled nonflammable transformer
Inventor: SAKAMOTO TAKESHI
IPC: H01F27/20
Filed: 1991-02-18
Abstract: PURPOSE:To increase the reliability of the isolation of an insulating gas sealed inside a tank from a liquid coolant in order to reduce the amount of use of a high-cost liquid nonflammable insulating coolant at a nonflammable transformer. CONSTITUTION:A plurality of spherical or rod-shaped balloon-shaped containers 7 in which an insulating gas 8 has been filled and sealed hermetically at their inside and which are composed of a flexible material are arranged and installed at the upper part of a transformer tank 1; the balloon-shaped containers 7 are housed in an insulating grid-shaped basket 10; they are hooked to the upper- part wall surface of the tank by means of insulating threads. When a transformer is operated and the temperature of a liquid insulating coolant 6 is raised, the liquid insulating coolant 6 compresses a balloon-shaped container 4 by its thermal expansion. A pressure inside the tank is raised properly; the saturation temperature of the liquid insulating coolant 6 is raised; the generation of air bubbles is suppressed. The containers in which the insulating gas has been sealed hermetically at their inside can surely isolate the liquid coolant from the insulating gas, and can be used for a long time with high reliability. The inside structure of the tank is simplified and a stray loss can be reduced.

Title: Inspection for junction condition of stitch bonding part
Inventor: HIROTA SANEYASU
IPC: H01L21/66
Filed: 1984-02-09
Abstract: PURPOSE:To enable to non-destructively inspect the junction condition of the stitch bonding part of a copper wire to a lead terminal by a method wherein the tip of a capillary chip is pressingly welded on the lead terminal and the size of an indentation, which is formed on the lead terminal by the pressure-welding, is inspected. CONSTITUTION:In case that a 25-mum diameter copper wire 6 is performed a stitch bonding on a silver plated lead terminal 4 by a thermocompression bonding method combined with an ultrasonic bonding using a capillary chip 5, the feed ultrasonic energy to the capillary chip 5 exceeds a specific value at a point. At that time, the tip of the capillary chip 5 is pressingly welded on the silver plated lead terminal 4, an indentation is formed and the configuration of this indentation becomes larger corresponding to an augmentation of the feed ultrasonic energy. Accordingly, after the stitch bonding was performed, whether there is any indentation due to the capillary chip 5 on the silver plated lead terminal 4 is inspected using a TV camera and so forth, and the size of the indentation can be measured. As a result, the junction condition of the stitch bonding part can be non-destructively inspected.

Title: Method for deciding intergranular stress corrosion cracking resistance of heat transmission pipe made of ni-base alloy
Inventor: YAMANAKA KAZUO
IPC: G01N33/20
Filed: 1988-02-02
Abstract: PURPOSE:To more exactly decide the stress corrosion cracking resistance of a heat transmission pipe made of an Ni-base alloy by measuring the conformable precipitation ratio of the chromium carbides precipitating at the grain boundary of said heat transmission pipe. CONSTITUTION:The precipitated carbides 3 assume 3 kinds of precipitation forms as shown by A-C when the heat transmission pipe made of the high-chromium Ni-base alloy is subjected to an annealing treatment at the temp. above the carbon solutionization temp. and is then subjected to a grain boundary strengthening heat treatment to precipitate the chromium carbides 3 at the grain boundary I after cooling down to room temp. A is the form in which the unsolutionized chromium carbides 2 are dispersedly formed within the grains and are precipitated non-conformablly with the base material. B is the form in which the carbides 3 are precipitated conformablly only in the base material on one side. Further, C is the form in which the carbides 3 are precipitated alternately matchingly in the base materials sandwiching the grain boundary 1. In the case of the alloy 690, the stress corrosion cracking resistance of said alloy is improved by subjecting the alloy to the annealing treatment at the temp. above the carbon solutionization temp., then cooling the alloy down to room temp. and subjecting the grain boundary strengthening heat treatment to precipitate the carbides 3 at the grain boundary I by holding for 15hr at 700 deg.C.

Abstract: PURPOSE: To increase the quantity of light incident on a light measuring means extensively without reducing the quantity of light incident on an image pick-up element, by leading the first light flux and the second light flux reflected by an image pick-up means and a reflecting means to the light measuring means. CONSTITUTION: The light flux A of a subject image is divided into a light flux B toward an image pick-up element 19 and a light flux C toward a total reflecting mirror 21 by a beam splitter 15, and thereafter, a light flux D and a light flux F reflected by the element 19 and the total reflecting mirror 21 are led to a light measuring element 25. As a result, the quantity of light incident to the element 19 is not reduced, and the quantity of light incident to the light measuring element 25 can be increased extensively.  In other words, since both the reflecting light of the beam splitter 15 and the reflecting light of the element 19 are injected to the light measuring element 25, a light flux of the incident light quantity larger than the conventional system is to be injected to the light measuring means 25, and as a result, the output of the light measuring element 25 is increased, and the influence by a disturbance such as a noise is hardly received.

Abstract: PURPOSE:To prevent the water leakage from a gap between a target seat and a flange by fitting a heating member to a target support member, and suppressing moisture from being formed into dew in a part exposed to the atmosphere. CONSTITUTION:A heater 21 is circularly formed as a heating member and fitted to the lower face of a flange 2, and the heater 21 is excited before the cooling water is fed to the cooling water passage 8 of the flange 2.

This state is maintained until the cooled portion becomes the same state as the space 13, then moisture can be suppressed from being formed into dew at the portion of the flange 2 exposed to the atmosphere. The generation of hydrogen peroxide is prevented, and the water leakage from a gap between the target seat 5 and the flange 2 due to corrosion is prevented.
